This is extremly annoying since it renders the generator unusable when aforementioned bundle is active. It always fails with this message:

[Doctrine\ORM\Mapping\MappingException]

No identifier/primary key specified for Entity 'Stof\DoctrineExtensionsBundle\Entity\Translation'. Every Entity must have an
identifier/primary key.

DDC-904 mentioned this should be fixed, but this is not true: bug is still found in latest Symfony2 git.
The docs only refer to using a single mapping format inside a bundle, but this does not work. Stof... uses xml mappings and it does not matter if i use yml or annotiations in a different bundle - the above error is still present.
